This is a pythonic wrapper around the libdc1394 Version 2 for FireWire Cameras.

(http://damien.douxchamps.net/ieee1394/libdc1394/) 

This work was primarily developped by Holger Rapp; I use this at work to do

freaky things (http://www.youtube.com/watch?v=5O4FrRujlII) and I consider it

usable and mostly bug free. The library sees some adoption, I am aware of 

a few other institutions that are using it now.

Included are also two GUIs. Both need PyOpenGL. 

- The first is writtin wxPython and no longer supported. It can display live

  images from a camera. An example is included. This needs wxpython. 

- The second is actively maintained and uses PyQt to display its data. It

  performs much better then the wxPython version. It depends on PyQt to be

  installed. 

Usage

=====

There are example scripts included. Basically there are two camera modes. The

first one acquires a number of pictures continuously (e.g. it is guaranteed

that no frames are missing when continously calling Camera.shot(). The other

mode is freerunning, the current image can always be accessed (thread safe) via

Camera.current_image. This mode is useful for visualisation or if you are not

interested in exact timings.  

Synchronized Cams

=================

Point Grey Research offers for their camera an auto synchronization when they

are attached to the same IEEE 1394 Bus. The SynchronizedCams Wrapper class

takes two cameras that need to be opened with the same framerate and mode.

SynchronizedCams.shot will then deliver two pictures taken at the same time.
